Answer 1

Answer:

a = 30, b = 12

Explanation:

(2√3 + 3√2) / 2√3 - 3√2

● Rationalising the denominator,

= { ( 2√3 + 3√2 )( 2√3 + 3 √2 ) } / [ (2√3 - 3√2) (2√3 + 3√2) ]

= (2√3 + 3√2) ^2 / [ (2√3)^2 - (3√2)^2 ]

☆ Using (a + b)^2 = a^2 + b^2 + 2ab identity in numerator and a^2 - b^2 = (a+b)(a-b) in denomimator.

= [ 12 + 18 + 12√6 ] / (2√3 + 3√2) (2√3 - 3√2)

= (30 + 12√6) / (2√3 + 3√2) (2√3 - 3√2)

● a = 30

● b = 12
